PAHs and mineral oils in rapeseed oil

Rapeseed oil is a vegetable oil obtained by pressing rapeseed. A distinction is made here between refined and cold-pressed oils. Cold pressed oils are produced without heat treatment and refined oils are obtained on the basis of different processing steps. Rapeseed oil contains omega-3 and omega-6 fatty acids and is mainly used for frying and baking.


Polycyclic aromatic hydrocarbons in rapeseed oil


In a recent test series, polycyclic aromatic hydrocarbons, or PAHs for short, were found in two samples. Benzo(a)pyrene (belongs to the group of PAHs) was detected – it is carcinogenic and mutagenic. It is produced by burning various plant products such as charcoal and can thus be found in water and soil.

According to Regulation (EC) No. 1881/2006, the maximum level for benzo(a)pyrene in edible oils is 2.0 µg/kg.


Eight samples with elevated values for mineral oil constituents


Mineral oil components can have mutagenic and carcinogenic effects. Eight of the 23 products tested had higher values. Presumably, these enter the foodstuff via lubricating oils or extraction agents. Currently there is no legal limit for mineral oils in food, but there is an orientation value of 13 mg/kg in oil, which was not exceeded in any product. The Federal Ministry of Food and Agriculture has already prepared a draft for a mineral oil ordinance, but there is currently no legal implementation.
